Values are means Â± SD. bANOVA comparison between all weight loss quartiles for all variables except sex. p-value for sex is from Chi-square test for the comparison of the distribution of sexes across all quartiles at baseline. Q1, Q2, Q3, and Q4â€”weight loss quartiles 1, 2, 3, and 4 respectively. Values are reported only for participants with gut microbiota data at baseline and also had weight measurements at week 12, i.e., non-dropouts
